...SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS LIKELY FROM
THE LOWER MISSISSIPPI VALLEY TO THE NORTHERN MID-ATLANTIC THIS
WEEKEND...

...HOT WEATHER FROM THE DESERT SOUTHWEST TO TEXAS...

A VAST AREA OF SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG A
SLOW-MOVING LOW PRESSURE SYSTEM THIS WEEKEND AS IT LIFTS THROUGH
THE OHIO VALLEY AND MID-ATLANTIC REGION. LOCALIZED AREAS OF HEAVY
RAINFALL WILL LIKELY DEVELOP ACROSS PENNSYLVANIA - POSSIBLY INTO
PORTIONS OF NEW YORK AND WESTERN NEW ENGLAND; WHICH WILL ELEVATE
THE RISK FOR FLASH FLOODING OVER THE NEXT COUPLE OF DAYS.
SCATTERED SHOWERS AND THUNDERSTORMS ARE ALSO FORECAST ALONG THE
TRAILING FRONT IN THE MIDWEST AND CENTRAL PLAINS. SOME OF THE
THUNDERSTORMS MAY TURN SEVERE OVER THE NEXT COUPLE OF DAYS,
HOWEVER, CURRENTLY THE THREAT IS MARGINAL AT BEST. PLEASE REFER TO
THE STORM PREDICTION CENTER`S WEBPAGE FOR UPDATES ON THE POTENTIAL
FOR SEVERE THUNDERSTORMS. MUCH OF THE GULF COAST AND THE SOUTHEAST
WILL HAVE SHOWERS AND THUNDERSTORMS DEVELOP EACH DAY DURING THE
AFTERNOON AND EVENING HOURS.

THE DESERT SOUTHWEST AND TEXAS WILL HAVE HOT TEMPERATURES UNDER
THE PERSISTENT UPPER-LEVEL RIDGE. MONSOONAL FLOW STREAMING INTO IN
THE REGION WILL AID THE GENERATION OF CONVECTION ACROSS NEW MEXICO
AND ARIZONA. MEANWHILE, NORTH OF THE BOUNDARY, COOLER TEMPERATURES
ARE EXPECTED THROUGH EARLY NEXT WEEK FOR THE UPPER MIDWEST AND
GREAT LAKES REGION.

NORTH OF THE FRONTAL BOUNDARY, A COOLER AND MORE PLEASANT AIR MASS
WILL BE ENJOYED ACROSS THE UPPER MIDWEST AND NORTHERN GREAT LAKES
REGION.  HOT AND DRY CONDITIONS ARE EXPECTED TO CONTINUE ACROSS
MUCH OF TEXAS WITH NO MAJOR FORCING MECHANISMS FOR ORGANIZED
RAINFALL EXPECTED. A DEVELOPING COLD FRONT WILL BRING COOLER
CONDITIONS FOR THE PACIFIC NORTHWEST THIS WEEKEND.
